WIRE DRIVE ROLL
The drive rolls installed with the POWER MIG® 216
have two grooves, one for .035”(0.9mm) wire and the
other for .045”(1.1mm) wire. Drive roll size is indicated
by the stenciling on the exposed side of the drive roll.
WIRE SIZE CONVERSION PARTS
The POWER MIG® 216 is rated to feed .025” through
.045" (0.6-1.1mm) solid or cored electrode sizes.
The drive roll kits and Magnum 250L gun and cable
parts are available to feed different sizes and types of
electrodes. See Accessories and Maintenance sec-
tions of this Instruction Manual.
PROCEDURE FOR CHANGING
DRIVE AND IDLE ROLL SETS
1. Turn OFF the power source.
2. Release the pressure on the idle roll by swinging
the adjustable pressure arm down toward the back
of the machine. Lift the cast idle roll assembly and
allow it to sit in an upright position.
3. Remove the outside wire guide retaining plate by
loosening the two large knurled screws.
4. Twist the drive roll retaining mechanism to the
unlocked position as shown below and remove the
drive rolls.

5. Remove the inside wire guide plate.
6. Replace the drive rolls and inside wire guide with a
set marked for the new wire size.
NOTE: Be sure that the gun liner and contact tip
are also sized to match the selected wire
size.
7. Manually feed the wire from the wire reel, over the
drive roll groove and through the wire guide and
then into the brass bushing of the gun and cable
assembly.
8. Replace the outside wire guide retaining plate by
tightening the two large knurled screws. Reposition
the adjustable pressure arm to its original position
to apply pressure. Adjust pressure as necessary.
